JACQI COMPTON, UF ELMIRA, NEW YORK.

Specification forming part of Letters Patent No. 39,887, dated September 15, 1863.

To (LZZ Awwm iztmny concern:

Be it known that I, .Moon COMPTON, of Elmira, in the county of Chemung and State of NewYork,have invented a new and Improved. Machine for Bending Folliesl for lheels; and I do hereby declare that the lbllowingis a full, e1ear,and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in whic Figurel is plan or top view of' my invention-5 Fig. 2, a side sectionaiview of the same, taken in the line .fr ,`Fig. l;A Fig. 3,/ an end view of the same.

Similar letters o t' reference indicate corre, spending parte in the several igures. t

The objectof: this invention is to obtain a felly-bending machine of simple construction, whichnwill .admit, by avery simple .manipulation or adjustment, of Y two,..d.ifferent-sized fellies being bent upon it. To this end the invention consists. in the employment `or use of a reversible former provided with two molds of difterent diameters, corresponding to the two different sizes of fellies to be vided with a shaft having mortises maude `in it to receive a lever, which is provided with a roller, and `the shaft provided with suitable bearings, all arranged as hereinafter set forth. t

To enable thoseskilled in the artto fully understand and construct myinvention, I will proceed to describe it.

A represents a framing, structed in any proper manner to support the working parts of the machine, and'B represents a former, which is placed horizontally on the framing A, and is secured thereto by bolts or screws, which pass up through the top bars, a, of the framing into 'tlie under side ofl the former, as indicated by the dotted lines in Fig. 3. The former B is-rather more than a. semi-circle, as will be seen by referring to Fig. 1,- and it has three dilt'erent diameters the central one, b,heing the greatest, and-c, which is at one side of b, being somewhat smaller than the one, d, at the opposite side of b, as shown clearly in Figs. 2 and 3. 'Theparts c d constitute the former proper, thecentral part, b, merely serving as a guide for a pressure-roller, C, which is attached to a lever, D, one end of which is fitted in avertical shaft,

and is allowed to turn bent, the fermer being pro.

which may be conit ,willbe'seen that` fellies E, which passes centrally through the former freely therein. This shaft E has the -journals e at its ends fitted in` bars F F', the outer 4ends of which are fitted inthe ends of avertical b ar, G, which is attached to the -former B by a horizontal arm, H. framing A, as shown in` Figs. l and 2. The lever Dis provided with a joint, f, which admits ofthe lever being raised up, as indicated by the red outline in Fig. 2.' To one end of the central part, b, of the formerthere is secured a metal plate, I, which i has two notches, gg', made in it-one in its upper and the other in its lower side-as shown clearly in Fig. 3.

The operation is as follows.: When the smallestV fellies -areto-be bent, the former B is in the position as shown in Figs. 2 and 3,

`.1 l.i,e...sxmallerzpart,or .mold c being uppermost.

The Telly J, being properly steamed, is s ecured at one end in the-notch g of the plate I by means of a key or wedge, It, and the lever D is turned so that its roller O will bea-r against the telly J'and bend it around the mold @andthe two ends of the felly are con-` nected by a bar, K, which is nailed to them and retains the felly in shape when removed rom the'mold c and placed on a rack to dry. In order to remove the bent felly from the mold the lever D is raised upward, as shown in red in Fig. 3, and the upper bar, F, removed. When the larger-sized fellies are to be bent,

the former B is detached from the framing A Y and insertedsothat the lai ger mold, d, will be uppermost. The lever D isthen inserted in another mortise in the shaft E, so that said lever will have the same relative position with the moldd that it had with the mold c. The lever Dfmay be varied'in length by adjusting it moreor less forwardin the shaft E, a key, c", beinggus'ed to secure the lever in its mortise in the shaft. ly is secured at one'endin the notch g in'plate I, said notch being then uppermost, as well as the bar F. Thus, by this simple arrangement, of two dierent sizesmy :be bent on one and the same machine. f

Having thus described my invention, what Iclaim as`new, and desire to secure by Letters Patent, is l.
